I have found their search interface for HN (https://hn.algolia.com) useful. They have a drop-down for selecting how you'd want to sort the results. From how I see it Google is doing more blackbox magic whereas Algolia is being a faithful/predictable search engine.

Probably because Algolia isn't using yet any machine learning, but more old-school (yet still very good) tries-based search.

And it's probably why also Algolia shines as search engine for a website vs searching the internet like Google. The former has a small scope (looking for videogames on twich, polo on lacoste) while the latter must be personalized for the user (the snake python vs the programming language python).
